Nested Resources

Toucan now handles nested resources set up in routes. For instance:

  routes.MapRoute(
    name: "PostComments",
    template: "Posts/{post_id}/Comments/{action=Index}/{id?}",
    defaults: new {controller = "Comments" });

We can then load and authorize the Post resource:

  [LoadAndAuthorizeResource(typeof(Post))]

The key is ensuring that the identifier for the Post resource is named with the type name, i.e. csharp post_id for a Post resource. The route data is examined first for parameters that match the type of the resource, if none are found it moves on to a simple id parameter. If none are found, it initializes a new model instance.
